W H R Rivers (1864-1922): the founder of research in cross-cultural perception.

This paper presents a brief review of Rivers's contribution to psychology, especially to his cross-cultural studies of the basic perceptual processes of vision, and examines the lasting influence of his findings. It reports briefly on the scientific milieu in which Rivers carried out his work and traces the growth of his interest in the psychology of perception from the early days of his medical work to his appointment as a foundation lecturer of two English universities, London and Cambridge. It is argued that Rivers's contribution has been undervalued by psychologists.
